PIGKER ROD AND STAND FoR LOOMS.

Application filed March 14 1923. Serial No. 625,038.

To all whom it may eoncem:

Be it known that I, VILFRID H. LUsIG- NAN, a citizen of the UnitedStates, residing at iVorcester, in the county of Worcester and State ofMassachusetts, have invented certain new and useful Improvements in aPicker Rod and Stand for Looms, of which the following is aspecification.

This invention relates to the art of textile machinery or looms, theobject being to provide novel improvements in loom picker rods andpicker stands.

In order to comprehend the invention, it is here explained that inlooms, especially those of the conventional .and well understood type,that the picker rod causes considerable amount of damage and loss oftime by becoming loose in the picker stand and which when tightenedcauses a binding action.

The prime object of this invention is to provide a picker rodwhich canbe securely locked into engagement with a picker stand against anypossibility of the picker rod becoming loose.

A further object of my invention is to provide a novel picker rod whichwhen once adjusted is always directly in the center of the stand, thuspreventing same from binding and becoming loose due to any frictionalmovement.

A still further object of my invention is to provide a picker rod with asafety device.

And a still further object of my invention is to provide an improvedpicker rod that can be easily connected to thepresent type of loom afterseveral minor changes have been made.

An additional object of the invention is to provide a picker rod andpicker stand which is simple in construction, durable, eflicient for thepurpose intended, and one that can be manufactured and installed onlooms at a relatively low cost.

Referring to the accompanying drawing which forms a part of thisspecification and which clearly shows the construction of my improvedpicker rod and stand,

Figure 1 is a side elevation of a picker rod and stand constructed inaccordance with my invention, showing the picker rod broken in two.

Figure 2 is an end view of the picker rod and stand.

Figure 3 is a section taken on line 3-3 of Figure 2, and

Figure 4 is a picker rod and stand.

Referring to the accompanying drawing in detail, like characters willbeused to designate like parts in the different views.

vertical section through the 'In the drawing, the numeral 5 indicates apicker rod formed of fibre, bakelite, or other similar material. Theupper end of the picker rod is provided with screw threads 6, which isadapted to pass through a screw threaded bore 7 formed in a picker stand8. A nut 9 mounted on the outer portion of the threads 6 and a springWasher 10 coact to securely lock the picker rod into engagement with thepicker stand and prevent any possibility of the picker rod becomingdisengaged or binding in any way. The outer end of the picker rod isprovided with a groove so that if desired the screw threaded portion maybe spread to provide additional locking means.

In order to mount the picker rod and stand onto a loom, the stand isprovided with a screw threaded recess 12 for. receiving a screw threadedbolt (not shown) carried by the loom. The recess 12 is formed in thestand at right angles to the threaded bore 7 V In View of the foregoingdescription of my invention, taken in connection with the accompanyingdrawing, it is thought that any further explanation as to theconstruction, operation, and objects of the invention is unnecessary.

While I have shown and described the preferred form of my invention, Irealize that various minor changes may be resorted to, without departingfrom the spirit and scope of the invention as claimed, and therefore, Ido not wish to limit myself to the exact details of construction shown.nor to the combination and arrangement of parts.

What I claim as new and desire to secure by Letters Patent is:

1. A device of the character described comprising, a picker rod, oneextremity thereof being screw threaded, a picker rod stand provided withan internally threaded bore adapted to receive the threaded extremity ofthe picker rod, a nut adapted to engage the extremity of the picker rodafter the same has been inserted through the stand, means for preventingdisplacement of the said nut, a screw threaded bore provided at rightangle to the first mentioned bore adapted to connect the stand upon theloom, and a boss formed on one side of the stand about the lastmentioned screw threaded bore.

2. A. device of the character described comprising, a picker rod havingscrew threads formed on one extremity thereof. a transverse grooveformed on' the extreme end of the threaded rod, a picker rod standhaving one side substantially forming a flat surface and the other sidecurved about the edges thereof, a boss formed on the flat side of thepicker rod stand, the central portion of the picker rod stand beingprovided with an internally threaded bore adapted to receive thethreaded extremity of the picker rod, a nut adapted to engage thethreaded extremity of the picker rod, a lock washer positioned betweenthe nut and picker rod stand and adaptedto prevent displacement of thesaid nut,' a second threaded bore formed at right angle to the firstmentioned bore and adapted to receive means for securing the picker rodstand upon the loom.

In testimony whereof, I have aflixed my signature in the presence of twowitnesses.
